Rooting the Light Phone 2 - Android Q&A, Help & Troubleshooting

Hey all!
I have a Light Phone 2 which uses Android 8.1. It's a neat little device that I'd love to tinker with. There is a detailed guide explaining the build process ontop of Android 8.1. The TL;DR is the Light Phone uses LightOS which is another word for an app that site on Android 8.1 that has lower-level access, similar to how the settings app works.
There is a medium post outlining the build process entitled Building LightOS with React Native. I cannot link to it as I do not qualify for the 10 post minimum. So you'll have to google it.
I can get to the Android recovery screen. Although from there I can't do anything. As adb is locked to only sideload and mounting the system produces no results on my Linux machine.
I realize very few people have this device and can comment from experience but does anyone have any idea how to go about rooting this phone? Or getting it to a state to begin tinkering?
Thanks!

Before starting to try to root phone's Android test whether you can enable these 2 options in Android's Settings -> Developer options:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If YES then you have to find a Custom Recovery matching your device what is prerequisite to flash any Rooting software.

Click to expand...
Click to collapse
Unfortunately, that is the thing, the phone does not have these settings available. I was hoping there would be a way to do this directly from the recovery menu

@kennethashley You can access the recovery menu by power and volume up at the same time. When you reach the screen that says "no command" press power first, then volume up, then quickly release volume up first then power. There, you should be able to put the phone into recovery mode.
you can then put the phone into fastboot mode and use adb tooling to enable oem unlocking so you can root the device.
